Application led October 27, 1925. Serial No. 65,163.

terior of the bowl will not become caked with nicotine and' tobacco particles, which is now the case after continued use of the pipe.

The primary object of theinvention is to provide a cleaner lthat is associated permanently with the pipe for permitting ofn the cleaning of the bowl thereof, without the agency of any separate tool or implement.

A further object of the invention is to provide a cleaner of this charactenthat may be associated with a pipe of conventional form without modifying the construction of the pipe to any considerable extent and that ma. be also so constructed asto be associated wit pipes that carry a removable bowl construction.

With the foregoing and other objects in view as thev nature of the invention will be better understood, the same comprises the novel form, combination and arran ement of parts hereinafter more fully escribed, shown in the accompanying drawing and claimed:

In the accompanying drawing, wherein like 'reference characters indicate corresponding parts throughout the several views:

Figure .1 is a fragmentary sectional view of a conventional formcf pipe with which is associated my novel cleaner',

Figure 2 is a top plan viewof a pipe equipped with a removable bowl construction within which bowl construction is disposed my novel cleaner and Figure 3 is a longitudinal section through Figure 2, a portion of the pipe construction being shown in elevation.

First having reference to Figure l, the' pipeshown therein includes a bowl 5 and,

stem 6, and in order to adapt this form of l pipe to a cleaner constructed in accordance with this invention, said bowl portion is formed exteriorly at its upper edge with a circumferential rove 7 for a purpose hereinafter more fully described.

My improyed cleaner constitutes the prol, vision of a single strip of relatively narrow and thin sheet lmetal, preferably of aluminum, 8, that is'bent into general U- shape as formed. The legs and connecting portion of this U-shaped member are adapted to have close contactwith the interior of the bowl in order that the edges thereof will scrape from the interior any matter that may collect thereon during the operation of the cleaner. The U-shaped strip is secured for rotation within the bowl through the medium of a rivet 9 that passes through the connecting portion and bottom wall of the bowl, as shown.

The upperl ends of the legs 8 of the U- `shaped-"cleaner strip are formed with laterally extending portions 10-10 thatengage over the upper edge of the bowl and that are formed with downwardly extending and inwardly bent portions 11-11, 12-12, that engage the side of the bowl and within the circumferential groove Zuffor preventing any wobblingof the cleaner upon its pivot 9 which would otherwise impair the eicient operation ofthe device, the portions 12-12 engaging within the grooves preventing any tendency of the side legs of the cleaner member 8 from disengaging the inl terior surface of the bowl during the cleaning operation.

n the form of the invention shown in Figures 2 and 3, the pipe bowl 5 is formed at lts upper end with internal threads 13 and adapted for threaded insertion within the bowl and preferably in spaced relation to the lower portion thereof is an auxiliary bowl 14 of suitable sheet metal that isof the general shape of the pipe bowl 5', and that is formed at its upper c dge with a flangel l5 for close engagement with the upper edge of the bowl for limiting the inner threaded engagement of the auxiliary bowl 14 with the pipe bowl 5.

'In this form of the invention, the cleaner element 48 is also formed from a single length of sheet metal 'being bent into U-formation, for association within the auxiliary bowl 14, the lower connecting portion thereof being swivelly connected to the bottom of the auxiliary bowl through the medium of a rivet 16, in order that the cleaner may be freely rotated within the bowl vfor cleaning the sidewalls thereof after each smoke.

The upper ends of the legs of the cleaner 8 are extended outwardly overthe auxiliary bowl ange 15 as at 10-10, and then downwardly and inwardly at 12-12 for engagement within a rabbet formed at the perimeter of the under side of the auxiliary bowl flange 15, for similar purposes to the like construction of the form shown in Figure 1.

s tongue 21 in opposed relation with the extension 20 for frictional engagement between the ears or lugs 17 for maintaining the cover in closed position.

The vertical lugs of the portions 10-10 of the cleaner 8, shown in Figure 1, provide finger engaging elements whereby the cleaner may be turned about its axes in the cleaning of thelbowl, while the ears or lugs 16 and 17 of the lform of the invention shown in 20 Figures 2 and 3 are provided also for this additional function, and it will readily be understood that I have provided a highly novel and eicient form of cleanerthat may be associated with a multiplicity of pipe constructions without materially altering the same. v

My improved cleaner may be adapted for other pipe constructlons than those shown 11i the drawlngs, and also minor changes may be made in the invention per se without departing from the spirit and scope of the appended claims.

I-Iaving thus described my i invention,

.what I claim as new and desire to secure cover for the auxiliary bowl in the form of a disk that has pivotal connection with the upper end of one of the legs of the U-shaped member.

2. In a` cleaner for smoking pipes provided with a removable auxiliary bowl, a U-shapedmetallic strip adapted for insertion within the auxiliary bowl, a pivotalconnection between the lower portion of the U-shaped strip and the bottom wall of the auxiliary bowl for facilitating the movement of the strip Within the bowl, a cover for auxiliary bowl in theform of a disk that has pivotal connection with the upper end of o'ne of the legs of the U-shaped strip, and means carried by the upper end of the other leg of the U-shaped strip whereby the cover disk may be maintained in closed position.

In testimony whereof I affix my signature.
